执行校验的时候：

[WXApi checkUniversalLinkReady:^(WXULCheckStep step, WXCheckULStepResult* result) {

        NSLog(@"%@, %u, %@, %@", @(step), result.success, result.errorInfo, result.suggestion);

    }];

日志如下：

wxlog:set property list

wxlog:launch app with ul only success

wxlog:Successfully starting WeChat with the universal link.

wxlog:Error:universal link check enable but contextId is error., contextID:(null)

 wxlog:Error:set token fail, errCode:3, errLog:app no context, req[(null)], contextID[(null)]
